|MAXI J1631-479: Shin2019 reported a possible counterpart (VPHASDR2 J163114.1-474822.7) with i’=18.3. However it showed no optical variability compared to their observations (R ~ 19.1 and I ~ 18.0).
Later, Kong2019 detected another target 1.4” from the radio position with r’=19.36 ± 0.06 (calibrated against APASS) and R=18.13 ± 0.03 in DSS images from 1992.
The possible counterpart seems to be an interloper unrelated to the X-ray transient
